Agent Evaluation Reliability: More Tasks Won't (Always) Fix An Agent Leaderboard

Michael Hardy, Ruhana Azam, Anka Reuel +2

Agent evaluations are increasingly used to compare LLMs and inform deployment decisions, yet ranks can reflect not only the model but also the effects of the evaluation conditions…

Evaluation Cards: An Interpretive Layer for AI Evaluation Reporting

Avijit Ghosh, Anka Reuel, Jenny Chim +45

AI evaluation results are produced at scale but reported inconsistently across leaderboards, model cards, benchmark papers, and company blogs. The cost is interpretive: readers can…

AI Cartography: Mapping the Latent Landscape of AI Benchmark Ecosystems

Michael Hardy, Anka Reuel, Lijin Zhang +6

While aggregate leaderboard scores drive AI development, they contain substantial measurement noise whose sources and magnitudes remain unquantified, making it unclear when ranking…

Knowledge without Wisdom: Measuring Misalignment between LLMs and Intended Impact

Michael Hardy, Yunsung Kim

LLMs increasingly excel on AI benchmarks, but doing so does not guarantee validity for downstream tasks. This study contrasts LLM alignment on benchmarks, downstream tasks, and, im…

Efficient Detection of Bad Benchmark Items with Novel Scalability Coefficients

Michael Hardy, Joshua Gilbert, Benjamin Domingue

The validity of assessments, from large-scale AI benchmarks to human classrooms, depends on the quality of individual items, yet modern evaluation instruments often contain thousan…

Autoscoring Anticlimax: A Meta-analytic Understanding of AI's Short-answer Shortcomings and Wording Weaknesses

Michael Hardy

Automated short-answer scoring lags other LLM applications. We meta-analyze 890 culminating results across a systematic review of LLM short-answer scoring studies, modeling the tra…

Refactor Analysis: Predictive Evaluations of Factor Models and Dimensionality

Michael Hardy

Unidimensional factor models justify some of the most consequential summaries in science -- single scores, single ranks, and single leaderboards -- yet unidimensionality is usually…

Fantastic Bugs and Where to Find Them in AI Benchmarks

Sang Truong, Yuheng Tu, Michael Hardy +8

Benchmarks are pivotal in driving AI progress, and invalid benchmark questions frequently undermine their reliability. Manually identifying and correcting errors among thousands of…

Interpretability from the Ground Up: Stakeholder-Centric Design of Automated Scoring in Educational Assessments

Yunsung Kim, Mike Hardy, Joseph Tey +2

AI-driven automated scoring systems offer scalable and efficient means of evaluating complex student-generated responses. Yet, despite increasing demand for transparency and interp…

Measuring Teaching with LLMs

Michael Hardy

Objective and scalable measurement of teaching quality is a persistent challenge in education. While Large Language Models (LLMs) offer potential, general-purpose models have strug…

"All that Glitters": Approaches to Evaluations with Unreliable Model and Human Annotations

Michael Hardy

"Gold" and "ground truth" human-mediated labels have error. The effects of this error can escape commonly reported metrics of label quality or obscure questions of accuracy, bias,…
